Toilet foam apparatus

A toilet, comprising:

• a toilet body, comprising a toilet surface;
• and
• a toilet foam generating mechanism disposed in the toilet body, the toilet foam generating mechanism comprising:
• a foam generating cavity, comprising a foam outlet;
• a foam spray nozzle in communication with the foam outlet and facing the toilet surface;
• and
• a foaming liquid adding passage in communication with the foam generating cavity, the foaming liquid adding passage comprising:
• a foaming liquid chamber;
• and
• a liquid suction device, comprising a first end in communication with the foaming liquid chamber and a second end in communication with the foam generating cavity, wherein a power supply end of the liquid suction device is electrically coupled to a first switching power supply;
• and
• a controller communicably coupled to the first switching power supply,
• wherein the first switching power supply generates a pulse width modulation signal defining a volume of foaming liquid pumped into the foam generating cavity is associated with a structure size of a toilet foam being generated is adjustable between a small size and a large size.
